Update naming of Vercel token + add vercel.json (#267)

## Problem

The latest test run of the new e2e Edge testing CI failed with the
following error:

> Error: Input required and not supplied: vercel-token

The first solve I think might resolve this error is to change the naming
of the Vercel token from `VERCEL_TOKEN` to `vercel-token`, as it is in
the example yamls in [the Vercel GH action's
repo](https://github.com/amondnet/vercel-action?tab=readme-ov-file#method-2---via-verceljson).

I also noticed while reading the Vercel GH action's repo that I didn't
add a `vercel.json` file, which seemingly is needed to properly deploy a
Vercel project via GH actions. So, this PR adds that as well. Info about
`vercel.json` here:
https://vercel.com/docs/projects/project-configuration#functions.
